I'm adding a little information about the whole 1D, 2D, 3D, and 4D splits..I've been asked recently and a thread was started about it so I figured I'd add it here..
I stole this from Bubba because she's not here to post it and it's a very good example.
1D = fastest time of the day
2D = fastest horse that is equal to or slower than the agreed-upon split (typically 1/2 second from the 1D time)
3D = fastest horse that is equal to or slower than the agreed-upon split (typically 1 second from the 1D time)
4D = fastest horse that is equal to or slower than the agreed-upon split (typically 2 seconds from the 1D time)
Here is a link that have actual show results that you can read through and get a feel for the "D"s

I actually believe I may make a video about it..I can't find a good one on youtube and I can explain it better in words than I can writing it down..
